Best AI Tools for Math Students (Free, Tested 2026)

By Leo Chen · Last reviewed September 2026 · Written from a student perspective · How we test

I did first-year maths the wrong way round. I learned that a graphing tool could draw the function, and I let it draw the function instead of drawing it myself first. Then in the exam there was no Desmos, and I discovered that I had learned to read graphs, not to reason about them.

That is the specific trap with maths tools, and it is worth stating plainly before any recommendations: in every other subject, a tool that does part of the work for you is just efficiency. In maths, the work is the understanding. So the entire question is which parts of the job you hand over, and in what order.

Here is how I would set the stack up now, organised by what you are actually trying to do rather than by which app is best.

The four jobs you will actually have

Almost everything a maths student does falls into one of these. The tool matters less than knowing which one you are doing.

1. Picturing something you cannot see

This is the safest place to use a tool, because visualizing is not the assessed skill - understanding what the picture means is.

• Desmos for quick function plotting and sliders you can drag
• GeoGebra when you need geometry, 3D surfaces or matrices alongside the graph

Both are completely free with no account. Use them to check your mental picture against reality, not to build the picture in the first place.

2. Checking work you have already finished

The order here is the whole point: do the problem, then check it. Not "look up the method, then reproduce it", which is how most people actually use these and why they feel like they are learning nothing.

• Wolfram Alpha when the answer must be exactly right - integrals, limits, series
• Symbolab when the steps are what you got wrong and you can compare them against yours
• Photomath for the same thing when the problem is on paper

I compared all of these properly in the free maths solver comparison, including which ones paywall the working.

3. Writing it up

Nobody warns you that a maths degree becomes a writing degree around second year.

• Overleaf for LaTeX - free tier is more than enough for undergraduate work
• Zotero to keep the references straight once you are citing

Start from a template, not a blank document. That is the difference between a weekend and a month of frustration.

4. Reading the paper you were assigned

• SciSpace for dense papers, because it explains notation in place
• Connected Papers when you have one relevant paper and need the five around it
• Consensus when you want to know whether a claim is actually agreed on

The order matters more than the tool

This is the bit that decides whether any of the above helps you:

1. Attempt the problem with nothing open
2. Get stuck, and write down exactly where you got stuck
3. Visualize that specific step - not the whole problem
4. Only then check the answer, and read the first step that differs from yours

Step two is where the learning happens and it is the step everyone skips. If you go straight to a solver, you get a correct answer and no information about your own understanding, which is a bad trade even when the answer is right.

Falling into this pattern is not a discipline problem either - it is what the tools are designed to encourage, because a solver that returns an answer in two seconds is much more pleasant to use than one that makes you sit with being stuck.

The tools change by year, more than you would expect

The jump that catches people is first to second year. The tooling that carried you through calculus is close to useless for analysis, because there is nothing to plot and the answers are not numbers. What you need instead is somewhere to write LaTeX and a way to test whether you can still reproduce a definition from memory.

What I would install tonight, in this order

GeoGebra (free, five minutes, immediate benefit) → Anki (free, and the only tool here that fights forgetting) → Overleaf (free tier, start it before you need it rather than the week a proof is due) → one solver for checking, and treat it as an answer key rather than a tutor.

If your course involves any computation - and by third year it usually does - the GitHub Student Developer Pack gets you Copilot and a stack of paid development tools free while you are enrolled, which is the single highest-value free claim on this site.
